How to fix Total size of pipeline parameters exceeds maximum allowed error and use dynamic headers in HTTP client snap

"Total size of pipeline parameters (44548442) exceeds maximum allowed (8388608)" error or how to create dynamic header value in HTTP client snap. Hi, Got this errors when I got a input document with too much (lines x columns) -- too much is weird because i am tlaking about less than 1meg csv files at the end. My flow is the following : 1/ A pipeloop calling a child pipeline. 2/ the child pipeline extracting data from SAP and than pushing the data into a google cloud storage through a http client in another child pipeline. 3/ why in another childpipeline : because we need to get the filename dynamic (in a query parameter) and reuse the name in another snap after the upload. (we can only put some _variable and no _variable anyway we can't catch the value after the http client snap. Question 1 : anyway to avoid the exceeds maximum allowed (8388608) error? Question 2 : anyway to push a $variable in the settings of http client and reuse it in a snap just after?
